Describe the solution you'd like
When I ran "poker_ai cluster" with an invalid set of values, the code first created combos of flop/turn/river (takes ~3 minutes), and then validated the inputs. I think it will help folks have faster iterations with the code base if validation happens before the creation of combos.

ValueError: Preflop lossless abstraction only works for a short deck with ranks [10, jack, queen, king, ace]. What was specified={2, 3, 4, 5, 6} doesn't equal what is allowed={10, 11, 12, 13, 14}
